SPECIFICATION forming part of Letters Patent No. 718,280, dated January 13, 1903.

Application filed May 13, 1902.

' To all whom it may concern:

Be it kn own that we, DAVID ROSENBERG, re

siding at Providence, and ROMEO CHARTIER,

residing at Oenterdale, in the county of Provi- 5 dence and State of Rhode Island, haveinvent ed certain new and useful Improvements in Hat-Polishing Machines; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to machines for cleaning and polishing hats; and the object is to provide a simple and easily-operated machine which may be readily adjusted to fit any size of hat and by the use of. which hats may be cleaned and polished and restored to their original color.

It is fully described and illustrated in this specification and the annexed drawings.

Figure 1 shows a perspective view of the machine. Fig. 2 is a sectional elevation of the head on line 2 2 of Fig. 3, also showing the frictional wheels for driving, Fig. 3, and the friction-pulleys for driving. Fig. 3 is a plan view showing section on line 3 3 of Fig. 2. Fig. 4: is a perspective view of one of the parts of the form. Fig. 5 is a top view of the revoluble plate.

In the construction of the machine, A is the standard or column, supported on radial feet B.

E is the tool-box, held on one side of the standard.

F is the gas-heater, projecting outwardly from the upper end of the standard. A vertical shaft G, journaled in the standard, supports the plate on its upper end and has keyed to it on its lower end the small bevel friction-wheel H. This small wheel engages a similar wheel I, larger in size, mounted on a short shaft J, and is revolved by the power being applied to a foot-treadle K through the connection m to a crank M.

The adjustable head is made in two halves R and S and mounted on the revoluble plate 0. Projecting outward from a boss on the inner side of these forms is a pin D, which extends into the hub on the plate 0 and around which is a coil-spring e, acting to keep the halves apart.

The guide and stop pin. f projects down- Serial No. 107,083. (No model.)

ward from the under side of the forms into the guide-slot g in the plateO and also limits the outward motion of the forms by bringing up against the end of the slot. The crown-plate N is fitted to bear on top of the two halves to cover the space between them and has a guide-stem projecting down into the center of the hub or plate 0.

In applying the hat to theform the two halves are drawn together by a slight pressure of the hands until the hat will fit over them. 'Then they are released and in separating bear against the inside of the hat and hold it in place over the center of the shaft. The hat is then revolved very rapidly, and the centrifugal force acting on the blocks holds the hat rigidly in place while the pol 7o ishing and cleaning are being done.

Having thus described our invention, we claim as our improvement and desire to secure by Letters Patent- 1. In a machine for cleaning hats, a head made in two halves mounted on a revoluble plate, guide-pins in said head, springs to keep the halves of said head apart, a revoluble plate slotted to receive said guide-pins, in combination with a shaft on the upper end of -which is mounted the plate, a small bevelwheel fixed to said shaft, a larger bevel-wheel engaging with said small wheel, and a crank, connection and foot-treadle for transmitting motion to the head, substantially as described. 8 5

2. In a hat-cleaning machine, the combination of a hat-block made in halves, pins extending longitudinally from each half of said block into the center hub, springs arranged on each of said pins to keep the halves apart, 9o guide-pins projecting from the under side of said blocks, a plate slotted to receive said guide pins, a vertical shaft on which said plate is mounted, a small friction wheel mounted on said shaft, a larger friction-wheel 9 5 engaging said small wheel, a foot-treadle, connection and crank for actuating said wheels, substantially as described.

In testimony whereof we have hereunto set our hands this 8th day of May, A. D. 1902.

DAVID ROSENBERG. ROMEO CHARTIER.

In presence of M. L. HAZARD, HOWARD E. BARLOW.
